4.0 Installation and Upgrade Issues

This section describes known issues for installing or upgrading Dynamic File Services.

4.1 The Service Controller Does Not Start After an Upgrade

After upgrading from Dynamic File Services 1.0 or 1.5 to Dynamic File Services 1.6, the Service Controller might not restart automatically.

To resolve this problem, manually start the Service Controller. Administrator privileges are required.

  1. In a Windows Explorer browser, navigate to the folder where you installed the Dynamic File Services software.

    The default location is the C:\Program Files\Dynamic File Services folder.

  2. Double-click the DswServiceController.exe file.

    If you are prompted for credentials by Windows User Account Control, provide the username and password of a user with Administrator privileges on the computer.

    The Service Controller starts and its icon appears in the Windows notification area.

4.2 Disabling Simple File Sharing on Windows XP

You can test Dynamic File Services features on a Windows XP workstation by installing the Service component along with the Management component. Using the Service component on a workstation is allowed for testing purposes only, and is not supported for a production environment. In order to use the Service component on a Windows XP computer, you must disable simple file sharing.

By default, simple file sharing is enabled on Windows XP computers if the computer is not a member of an Active Directory domain. Simple file sharing allows you to easily share folders in a workgroup, but you cannot prevent specific users and groups from gaining access to your shared folders. If simple file sharing is disabled, you can specify which users and groups have access to shared folders on your computer, and those users must provide a password to gain access to your shared folder.

When you run the Dynamic File Service on a Windows XP computer, the Windows simple file sharing feature must be disabled. This allows the Service to control access to files and folders in a pair. You cannot set up pairs and policies until simple file sharing is disabled.

To disable the simple file sharing feature:

  1. Use one of the following methods to open the Folder Options dialog box:

    • In the Control Panel, double-click Folder Options.

    • Open a Windows Explorer browser, then select Tools > Folder Options.

  2. In the Folder Options dialog box, select View to see the Advanced Settings options.

  3. In the Advanced Settings section, deselect the Use simple file sharing (Recommended) check box.

    This is usually the last option in the list.

  4. Click Apply to All Folders, then click OK to apply and save your changes.

5.0 Known Issues

This section contains known issues in this release of Dynamic File Services.

5.1 Remote Merged View for a Windows Client Fails with NetApp

When using a NetApp Filer as the Secondary share path in a Dynamic File Services pair with a Windows 2008 Server as the Primary share path, the merged view fails for a Windows Client using SMB2 (such as Windows 7 or Windows Vista computer).

To work around this issue, you can do one of the following:

  • Enable SMB2 on the NetApp Filer.

    We tested NetApp Release 8.0.1RC3X167-Mode to verify that this solved the problem.

  • Disable SMB2 on the Windows 2008 Server running Dynamic File Services that hosts the Primary Share, then enable SMB1 on the Windows 2008 Server.

  • Disable SMB2 on the Windows Client (Windows 7 and Windows Vista).

For information about how to disable SMB2 and enable SMB1, see Section 5.3, Network or File Permission Error When Saving a File from Microsoft Word 2007/2010.

5.2 Service Can Hang When the Service Is Stopped or Restarted

If you are using SMB2 on the server and attempt to stop or restart the Dynamic File Service without first quiescing the service as described in Prerequisites for Stopping or Restarting the Service, the Service cannot be stopped and the Service hangs.

To avoid this problem, do not stop or restart the Dynamic File Service while the Service is scanning pairs, the Enforcer is moving files in a policy run, users are accessing files via the merged view, or management tasks for pairs and policies are in progress.

Quiescing the Service before stopping or restarting it is required for both SMB2 and SMB1. However, the Service hang issue does not occur for servers using SMB1.

5.3 Network or File Permission Error When Saving a File from Microsoft Word 2007/2010

An error might occur when a user attempts to save a file from Microsoft Word 2007/2010 when the source file resides on a local secondary location in a pair. The error message is:

There has been a network or file permission error. The network connection may be lost. (path\filename)

This problem has been observed when Dynamic File Services is running on a Windows Server 2008/2008 R2 server that is configured with SMB2.

The problem does not occur on Windows Server 2003 servers. The problem does not occur on a Windows Server 2008/2008 R2 server that is configured with SMB1. This issue also does not occur if the documents reside on the primary volume.

To avoid this problem, you can configure the local secondary location like a remote secondary. This option works only if the secondary location is on a different drive than the primary. Create a share at the secondary path, publish the share in Active Directory, then use the UNC path (\\server\secondary_share such as \\\secondary) for the secondary location when you create the pair.

To avoid the problem if the Windows Server 2008/2008 R2 server is using SMB2, you can make sure that your policies do not move documents to a secondary location that might be edited with Microsoft Word 2007/2010. For example, documents for archival can be moved, but not documents that are active.

To avoid the problem if the Windows Server 2008/2008 R2 server is using SMB2 and you want to store Word documents on the secondary location, you can downgrade the server-side SMB from SMB2 to SMB1:

  1. Log in to the server as a user with Administrator privileges.

  2. At the command prompt, open the Registry Editor by entering

  3. In the Registry Editor, go to the following location:


  4. Create a DWORD value named Smb2, then set its value to 0.

    This disables server-side SMB2 on the server. (A value of 1 enables SMB2.)

  5. If there is no value named Smb1, create a DWORD value named Smb1, then set its value to 1.

    This enables server-side SMB1 on the server. (A value of 0 disables SMB1.)

  6. Exit the Registry Editor.
